Finally I can online from home. I just received my new usb modem (air card) last week. I bought it from lelong for RM605 including delivery. Quite cheap compare if we buy it from computer shop outside there.

Sierra 875U

You can read the details about this model 875U modem here. Why I choosed this model because its a bit cheaper usb modem compare to Huawei E220 and the most important is from user experience ( I read frorm forum and blog) this modem is better from E220 in term of receiving the wireless signal.

In my residential area, I’ve managed to got 3G signal with weak signal (1 bar) but sometimes can up to 3 bar. Normally the signal between -102dBm to 93dBm only. I think its quite ok for me but I hope Celcom will upgrade their signal to be full bar at my area.
